Given below are two statements:

I:  Biot-Savart's law gives us the expression for the magnetic field strength of an infinitesimal current element \(I(dl)\) of a current-carrying conductor only.
II: Biot-Savart's law is analogous to Coulomb's inverse square law of charge \(q,\) with the former being related to the field produced by a scalar source, \(Idl\) while the latter being produced by a vector source, \(q.\)


In light of the above statements choose the most appropriate answer from the options given below:

1. I is incorrect and II is correct.
2. both I and II are correct.
3. both I and II are incorrect.
4. I is correct and II is incorrect.
